When is an out of service lock used?
When a piece of equipment is required to be placed out of service, a departmental “Out of Service Lock” (OSL) and Out Of Service tag is to be placed on the equipment’s power source.

What is a lockbox and how/when is it used?
A lockbox can contain several keys to locks that can be used when locking out multiple pieces of equipment and has slots to apply multiple locks to the box itself. This allows multiple individuals to lockout multiple pieces of equipment and the locks of each piece of equipment is contained in the box - these locks are lockbox type locks and not personal employee locks. The box itself is locked by employees personal locks.

•Dust build up
•Dropping tools
•Accidental Touching

Name and explain the 7 steps of LOTO
1.NOTIFY all affected employee(s) of LOCKOUT and reason.
2.SHUTDOWN the equipment using normal stopping procedure(s).
3.ISOLATE energy source(s). Dissipate and restrain stored energy.
4.LOCKOUT energy isolating device(s) with your assigned lock(s). Ensure the energy isolating device cannot be turned on while in the locked position.
5. Ensure safety of personnel. Operate push buttons to TEST/JOG isolation and then turn controls to “OFF” position.
6. After servicing equipment, CHECK to ensure no one is exposed and guards are installed
7. Remove lockout. RE-ENERGIZE
What is the difference between fall prevention and fall protections, give an example of each
Prevention: Eliminates the risk of falling through task redesign, barriers and administrative controls
Examples: Fall Restraint Systems, Guardrail Systems, Warning Lines
Protection: Allows a worker to fall, trusting a fall protection system to stop the fall before hitting the ground or next level
Example: Fall Arrest Systems
Name 5 things that trigger a critical lift as per the model program
1. Increased potential or risk of injury due to increased number of people involved in the lift.
2. Any lift requiring more than one crane.
3. Below the hook weight exceeding 95% of the rated capacity for fixed hoists or cranes. Below the hook weight greater than 75% for mobile cranes.
4. The load being lifted has a single surface area (i.e. – one side) greater than 400 sq. ft.
5. Any lift that causes plant operation interruption.
6. Where the load plus rigging exceeds 10 tons.
7. Any lift where engineering assistance is required to determine the weight and the weight estimate requires engineering judgments or assumptions.
8. Any lift assembly that incorporates non-ordinary lifting gear.
9. Lifts that are made where the crane or load are placed over buried utilities, or within 20 feet of the prohibited zone around overhead power lines.
10. Any lift where outrigger pads have a questionable support base. For example, soils which have limited load bearing capacity such as recent fill or disturbed soil, ground within 20 ft. of an excavation, trench, shoring, or on structures of unknown floor loading capacity.
11. Any lift utilizing a helicopter.
12. Any situation deemed critical by the person in charge, rigging supervisor, project manager, and project engineer or plant manager.
